Raonic return of serve.

I'm watching him play bagdatis who is only serving at 35% 1st serve percentage which was actually 19% for most of the set. Yet he has faced no break points and won 92% on first serve and 75% on second serve and he is just happy just to roll the second serve to the raonic backhand knowing full well he dominate the point from there. I know raonic is still working on his return but it is truly awful for a pro.
